UnityFileDownloader☁️

A file downloader that handles asyncronous and concurrent file downloading, implicit multi-part file downloading, pausing/restarting, properties with per-file granularity and more. ## Appendix This file downloader was built because UnityWebRequest and recent solutions built by Unity and third-parties are subpar and bare of features. While this project is written 100% in C#, this downloader should support all platforms that Unity does. If you have any feedback, please reach out to me at jpgordon00@gmail.com, or submit an issue or pull request. Collaboration is encouraged! ## Features - Concurrently download any amount of files while adhering to a fixed number of asyncronous tasks - Implicitly handles multi-part file downloading, including pausing/restarting of chunked downloads - Provides both task-based asyncronous methods and standard callbacks for errors, individual file completion, all file completion, and more - Granularity of properties can be on a per-file basis, providing the ability to pause/restart, and to get/set progress, timeouts, headers, callbacks and more - Optionally handle "atomic" file downloading by deleting all downloaded (partially or impartially) files and ability to continue downloading through HTTP/S errors - Code structure that allows for modularity of both download fulfillment (such as UnityWebRequest) and dispatching of downloads. ## Usage/Examples ```javascript using UFD; using System; // ... in some class public class Example { async void Download() { UnityFileDownloader ufd = new UnityFileDownloader(new string[] { "https://wallpaperaccess.com/full/87731.jpg", }); await ufd.Download(); } } ``` ## Issues - Unity Editor termination and application lifecycle methods do not stop this downloader from functioning. ## TODO The following features are some of which I deem to be deseriable and not currently implemented: - Dynamic chunk sizing based on download speeds - Cleanup of class structure to provide complete modularity of download fulfillment and downloader. - Provide alternative fulfillers to UnityWebRequest, perhaps unlocking better platform specific performance.
